This policy proposal has been accepted
The new RIPE Document is: ripe-509
This proposal describes how the RIPE NCC should distribute IPv4 address space from the final /8 address block it receives from the IANA. The proposal only discusses PA allocations; any other type of allocation or assignment is out of scope for this proposal.
The following policies come into effect as soon as RIPE NCC is required to make allocations from the final /8 it receives from the IANA. From then on the distribution of IPv4 address space will only be done as follows:
On application for IPv4 resources LIRs will receive IPv4 addresses according to the following:
a. Arguments supporting the proposal
The final /8 of IPv4 address space received from the IANA will have a special policy applicable to it in the RIPE region. This avoids the risk of one or a few organisations consuming the entire block with a well crafted and fully justified resource application. The proposal attempts to ensure that no organisation lacks real routable IPv4 address space during the coming transition to IPv6. It is very important that new entrants also have the chance to get some IPv4 space before it totally runs out because a small block of IPv4 addresses will be necessary for a while before the Internet can run on an IPv6-only platform.
b. Arguments Opposing the Proposal
IPv4 PI addresses will not be assigned through this policy.
Some organisations may believe and can demonstrate that their IPv4 requirements are larger than the minimum allocation or assignment sizes in the RIPE region. But this final /8 is not intended as a solution to the growth needs of a few organisations, but for assisting with the transition from IPv4 to IPv6.
Some organisations may set up multiple LIR registrations in an effort to get more address space than proposed. The RIPE NCC must be vigilant regarding these, but the authors accept that it is hard to ensure complete compliance.
Note: In order to provide additional information related to the proposal, details of an impact analysis carried out by the RIPE NCC are documented below. The projections presented in this analysis are based on existing data and should be viewed only as an indication of the possible impact that the policy might have if the proposal is accepted and implemented.
This proposal describes the distribution of IPv4 address space from the moment that the RIPE NCC would have to begin using the final /8 received from the IANA. It only provides for making /22 (PA) Allocations to LIRs and not for making any other kind of allocation or assignment. The final resource request which provides the "trigger" will not be filled from this final /8.
An LIR is eligible to receive one single /22 allocation provided they qualify for an additional allocation under the "normal" policy and have an IPv6 allocation from the RIPE NCC or upstream LIR.
A /16 of this final /8 will be reserved for "unforeseen circumstances". The "unforeseen circumstances" for which this /16 could be used are not defined in this proposal. This /16 will be used to make /22 allocations, if the rest of the /8 is used before a new policy is made for the /16.
The address space that is returned to the RIPE NCC after this policy comes into effect, will be re-allocated according to this same policy.
Address/Internet Number Resource Consumption:
After analysing the data that is currently available, the RIPE NCC does not anticipate that any significant impact will be caused if this proposal is implemented.
To prevent this policy from being triggered while there is still free space in other /8s, the final few "normal" requests will most likely be assigned and/or allocated as multiple, discontinuous prefixes. The last assignment or allocation will not be filled completely.
C. Impact of Policy on RIPE NCC Operations/Services
Current policies and procedures allow one organisation to set up and operate multiple LIRs, each with their own allocations. There are many organisations that do this. It is possible that some organisations will open multiple LIRs to obtain more than one /22. There is currently no basis for denying any organisation this right.
D. Legal Impact of Policy
This policy proposal has many similarities with the withdrawn policy proposals 2008-06 (Use of final /8) and 2009-04 (IPv4 Allocation and Assignment to Facilitate IPv6 Deployment)
The RIPE NCC has studied the legal implications of these previous proposals. The conclusions of this study have been published on the Address Policy Working Group mailing list:
